Hello, Others.

David Hoffman, filmmaker.

And I'm about to show you a clip from a film I made to help teenage boys understand testosterone.

I've been fascinated with testosterone ever since I was 13 years old and all of a sudden without warning, really.

I began to fight horribly with my mother not my dad, but my mom constantly blaming things on her.

My whole life changed, and no one really explained the effect of the hormone testosterone when it hits the body of a teenage boy.

You know, there was an A any film on testosterone, which was really interesting because this boy and this girl on nine years old at 10 years old and they're friends and all of a sudden when he's 13 he no longer can talk to her.

All he sees is breasts, lips.

He completely changes his friendship with her, which she does not understand, and he does not understand.

I experienced this.

I experienced an inability to really see girls for a while as beings other than sexual beings, because testosterone was in my body.

So before I run this clip, which was made for high school kids to understand testosterone I thought I'd give you a few facts.

Okay, Deeper voice.

You know about that buddy here?

Acne, bigger muscles.

You know about all of that?

Probably.

You also know that testosterone helps grow the prefrontal cortex of boys who without a prefrontal cortex, they can't see the future.

They just take risks all the time.

They just do stuff, and then later on, you find out.

Wow, that wasn't such a good thing to do because you don't have a prefrontal cortex till you're, I think 18.

Well, maybe even 23.

It's part of the reasons that boys are so dumb with a young and do such ridiculously wild stuff.

Drink and drive get into fights, all testosterone.

So I wanted to make something that could be running the schools that would help boys understand testosterone and my team and I made this little film you're about to see.

Does it help?

I don't know, but it's used by more than 1000 schools.

Pressure.

It's all in your head.

They say, do it.

They say, Try it.

They keep pushing.

The pressure is on.

Oh, Louis, you're going to Sheila's party.

Who's got the hot war?

It's getting intense in there.

What are you doing inside Lewis's head?

I'm going to show them what kind of pressure can build up inside someone's brain.

Come on.

Lewis's friends must be hassling him, so the pressure goes up.
